Abstract

Digital image analysis have been applied to determine and follow the body measurement, live weights, and animal growth. The objectives on this study were to compare linear body measurement (BMs) method (manually and digital image analysis) and to compare size and body dimension of Friesian Holstein (FH) and Limousin cows. In this study, the BMs of FH and Limousin cows was determined using digital image analysis (IA). Linear measurement of primary morphometrics, part of Columna vertebralis, and extrimity length of cows was first determined manually, by direct measurement. Then the digital images of cows were taken and the results obtained through the calculations were recorded into the computer and analized by Corel draw. Result showed that the BMs with both methods measurement was not significant different and IA method had lower coefficient variation (CV) than manual, which indicates the IA method can be used for morphometric study. For the body dimension, FH had larger frame size and lower body weight than Limousin. The different of breed caused differences in morphometric performances. FH had longer thoraxoc vertebrae, wither height, space between ischium, and space coxae to ischium than Limousin. Limousin had longer cervicalis vertebrae, sacral vertebrae, and scapulla.

Abstract

This study aimed to find out the compoSItion and distribution of thin-tailed sheep’s carcas tissue fed with green concentrate feed on the different breeding system. A total of 20 female thin-tailed sheep around 1 year old with an average initial weight of 18.3 ± 2.01, intenSIvely and semi-intenSIvely nurture for 119 days. Feed was given in the form of brachiaria humidicola grass and green concentrate with commercial concentrate as a control. Green concentrates and commercial concentrates are given in the morning at 07.00 and grass is given at 11.00, with a ratio of 40:60%. Concentrates were given with different nurture systems was carried out with four treatments, namely five sheep grazed for 6 hours with commercial concentrate feed (SIKK), five sheep grazed for 6 hours with green concentrate feed (SIIZ), five sheep grounded with grass feed and commercial concentrates (IKK), and five sheep are grounded with grass feed and green concentrate (IIZ). The experiment was carried out in a completely randomized factorial pattern with 2×2 treatments and 5 replications with initial weights as a correction factor. The results showed that sheep that were given green concentrates had lower weight, carcass weight, lower fat weight compared to commercial concentrates. However, with semi-intenSIve nurture it produces weight and percentage of muscle that is not much different from sheep that are given commercial concentrates.

Abstract

Bali cattle have a distinct coloration that indicates the sexual dimorphism of adult cattle. However, coat color deviations are found in bulls due to either genetic impurity or inbreeding. Furthermore, information is needed to determine whether there is a relationship between coat color and cattle performance. This study aimed to evaluate the potential association between coat color deviation and the growth traits of male Bali cattle. A total of 99 adult male Bali cattle from Livestock Breeding and Forage Centre (BPTU) Denpasar, Bali, were used in this study to assess the possible association between coat color and growth capacity. Animals were grouped according to color patterns into full black (FBL), faded black (FDB), black sorel (BSR), and sorel (SRL). Periodically, growth traits of body weight (BW), wither height (WH), body length (BL), and chest circumference (CC) were measured at birth, weaning, and 365 and 730 days of age. The repeated measurement Anova analysis was used to evaluate the relation between coat color and growth traits over time. This study showed no correlation for both traits in calves due to the absence of color deviation in age. However, it turned out to be a significantly positive correlation (p<0.05) when Bali cattle reached puberty at 365 and 730 days. The black adult bulls (FBL & FDB) were significantly larger in growth traits (p<0.05) than their brown (BSR and SRL) counterparts. The coat color of male adult Bali cattle was associated with their growth traits.
